I am very happy with the spell but I was curious as to how null gravity affects opponents within pilum range. I've tried to test it on two people; one with no burden and one that was encumbered. Neither noticed a change. So it promted my curiousity....Do they become more cumbersome the closer they get? Is there a chance they can resist it's affects? Are the affects so minor that it doesn't make a noticable change or perhaps the change to encumberence isn't displayed?

It's pretty significant. You weren't grouped with these people by the way, were you? Because encumbrance is referred to in ranges, it may not be noticable, but there is a definite effect. This effect increases the weight of all of their possessions, so the more encumbered a person is, the more the penalty. However, it doesn't have much effect on people who have very low encumbrance.

The actual proximity between you and the persons affected has no effect. They simply need to be within pilum or better._________________"Wise men talk because they have something to say; fools, because they have to say something." -- Plato
